raw-data-npm-vs-yarn.txt

Things that are important to us in a JS package manager
Yarn - NPM - Description
✔      ✔     1. Predictability -- will install the same packages every time
✔      ✔     2. Reliability -- it's not flaky / fail randomly
✔      ✔     3. Caching -- local installs wherever possible (less network traffic/bandwidth)
✔      X     4. Speed -- needs to be fast
✔      ✔     5. Cost of change -- needs to be manageable, both in terms of technical and also training-wise
✔      ✔     6. Feature: outdated
✔      ✔     7. Feature: interactive-upgrade
✔      ✔     8. Broad support -- works with React Native, Node CLIs, web, etc
✔      ✔     9. Community adoption -- can't be the reason people don't use Bowser
